The very first fusion band in Japan. The band is originated from the band formed by Akira Wada・Ken Watanabe・Daisaku Kume・Kohki Itoh・Katsutoshi Morizono・Rika Suzuki etc. in 1975. The band was selected as an opening act for the Eric Clapton's Japan tour in 1976. After heavy competition among record companies, the band signed with Polydor Records and released the 1st album “ PRISM ”.Upon its release, many fans queued up at the stores and sold out in many places. Following year, the debut concert was held at the Sugino Kodo Hall in Meguro of Tokyo. The fan made a line as long as it can reach Meguro station. It was such a sensational beginning for the band.
